So you are looking to move on. However, you need to know what you are moving on to. You need to know that quitting your current job is a prudent move by looking into other available positions. Do an internet search or look through the local want ads to determine if there is a demand for someone with your particular abilities and skill set.
Try looking at job websites like Monster.com, Indeed.com, or Simplyhired.com to see what sorts of alternative employment you can find. These sites offer a wide variety of jobs that are searchable by job type, pay grade, and state, city or region. Be sure to account for current living arrangements. If you are unable to move to a different area of the country, your job opportunities may be much more limited than someone who can pick up and move at any time. Be sure that you consider bonuses, insurance packages and other supplemental benefits when comparing your current position to potential employment opportunities.
